on the other hand if u want something better than stock factory...
try look for mxsteven: https://www.facebook...361641300680715 and reflash your ecu with better than stock factory mapping.... especially the spark plug coil dwell time...
Can stock ECU be re flashed and does it lose the re flash when battery current is terminated, example change battery?

any suggest at rawang or kota damansara?ECU is circuit tuning?so need to go for big factory?
btw is that waja stock factory not that good?
seri kembangan wasnt that far...plus..he is the only person have the custom rom (a.k.a custom software to configure stock 4g18 waja ecu without even factory can detect and no other mods needed)
stock waja is already good....i prefer 4g18 on waja instead newer campro (especially if compared to gen2)
Can stock ECU be re flashed and does it lose the re flash when battery current is terminated, example change battery?
yes only waja with 4g18 (mmc) ecu can be flash as far as i knew...the flash will not loose since its the rom...just like how factory put their mapping and various configuration in factory....
this steven guy is very good with electronics and used to have heavily modded waja....he is also a tuner and installer for megasquirt ecu (which some assembly required and not many people able to do that in malaysia)
this is his own car and works for reference: http://www.cardomain...03-proton-waja/

Nah! no one is stupid, you have just started your learning curve that is all. When I started out I didn't know nuts on cars too, that is why when I service my car, or getting it repaired I don't just drop it off to my mechanic but stay there and look at them do the work and most important ask questions....hahhaha
And through the years gain the knowledge. Then I joined the forum like what you have done. Ask your questions and learn from the replies.....
ECU re flash is to add some data into the OEM ECU. Not all ECU can do this, that is why I ask bro.rally on it. And once re flash on it, it stay as ROM means permanent and does not get erase when current is cut from the ECU. Some re flash are not permanent and when current is cut from the ECU it looses that data. Hope you understand my explanation....lol

For the brands of petrol there is non that is best. I have been in the forum for quite a few years and have read many posts. Different people having different cars are saying different brands works for their car, this means there is no one brand that is best. Even people with same brand car mentioned different petrol are best for their car, so again it shows no best petrol....hahhahha
For you I suggest you try the different petrol brands and see which works for your car. Probably 3 tanks full for each brand, this is for the car to adapt to that petrol. In the end stick to the petrol brand that works best for you.
For me I am using Petron and BHP. This is due to the stations being near my house, they have loyalty cards that I can change for free petrol and stuffs.....

Engine that can run on Ron95, running them on higher Ron does not help, just wasting money with higher fuel price.
Mileage can be due to many reasons. Driving style, route, weather, car condition etc., and even another waja may not be the same...
OEM ECU means the original ECU with original data. Not sure whether you can re flash back, this depends on the guy doing it
